In a method and apparatus for mass centering of a rotor, the unbalance of the rotor is measured and the result of the unbalance measuring operation and the weight of the rotor are used to determine the position of the axis of inertia which extends through the center of mass of the rotor, with respect to the axis of rotation thereof. The position of the axis of inertia is marked on an end face of the rotor by a marking tool. For that purpose, to bring the position of the axis of inertia and the marking tool into the appropriate relationship, relative displacement is produced by an actuating means as between the rotor and the marking tool in the radial direction with respect to the axis of rotation of the rotor, with the rotor or the marking tool being guided in the direction of displacement by a guide means disposed at an angle with respect to the axis of rotation of the rotor. The relative displacement produced in that way takes place within a linear region of action of the marking tool, which region extends through the axis of rotation of the rotor. The point at which the axis of inertia passes through the end face of the rotor to be marked by the tool can then be turned into the region of action of the marking tool for the latter to perform the marking operation.
